Liver disease, particularly hepatitis C, has emerged as a major cause of morbidity and mortality for people with HIV/AIDS in the era of potent antiretroviral therapy. Mortality is increased in patients with HIV–hepatitis C virus (HCV) coinfection compared with that in patients with HIV alone.1,2
The title of this column is the slogan from World AIDS Day 2006, and as we look to 2007 and a new Congress, a more appropriate slogan could not have been chosen. However, rather than keeping the promise, we are only slightly farther ahead than we were 1, 5, 10, or even 20 years ago and at some risk of going backward, as evinced by the sobering information made available through the World Health Organization (WHO) and the CDC.
Salivary gland enlargement, most commonly involving one or both parotid glands, is sometimes seen in association with HIV infection. Enlargement of the parotid gland may be due to diffuse infiltrative lymphocytosis syndrome; lymphoepithelial cysts; or malignant tumors, such as squamous cell carcinoma, Kaposi sarcoma, and Hodgkin and non-Hodgkin lymphomas.1,2 Non–HIV-related causes of parotid enlargement include acute and chronic viral infection, granulomatous disease, malnutrition, alcoholism, and diabetes mellitus.3,4 Here we report the case of a 41-year-old HIV-infected man with fat maldistribution syndrome associated with type 2 diabetes and hyperlipidemia. Sialadenosis developed presumably as a result of HIV infection and hypertriglyceridemia.
Shortly after the introduction of combination antiretroviral therapy, it was noted that a significant fraction of patients, from 8% to 17%, had poor CD4+ T-cell recovery despite suppression of HIV RNA to undetectable levels for at least 6 to 12 months.1
The authors report a case of adult-onset acute lymphoblastic leukemia (ALL) presenting with a right upper lobe infiltrate associated with acute fibrinous and organizing pneumonia (AFOP), which resolved spontaneously during the course of chemotherapy.
abstract: Pulmonary disease caused by nontuberculous mycobacteria (NTM) can be challenging to diagnose and manage. Patients typically present with nonspecific symptoms, such as cough and fever, and they often have underlying lung disease, which further complicates both diagnosis and treatment. To avoid treating pseudoinfection, the diagnosis should be based on a combination of the history and results of physical examination, radiographic imaging, and smears and cultures of at least 3 sputum samples. Occasionally, it is necessary to perform bronchoalveolar lavage or obtain tissue via transbronchial or open lung biopsy for histopathology and to assess for tissue invasion. Treatment involves a long course of often costly multiple antimycobacterial drugs. However, treatment with the second-generation macrolides, clarithromycin and azithromycin, has significantly improved cure rates for specific NTM infections. (J Respir Dis. 2007;28(1):7-18)

The authors report a case of idiopathic eosinophilic pneumonia in a man with sclerosing cholangitis and ulcerative colitis associated with features of sarcoidosis.
Asked to evaluate bilateral unexplained upper-thigh bruises on a profoundly impaired woman newly admitted to our rehabilitation unit 2 weeks after an intracerebral hemorrhage. Patient received high-dose dexamethasone to reduce perihemorrhage edema.
ABSTRACT: Irritable bowel syndrome (IBS) is characterized by abdominal pain or discomfort, bloating, and constipation or diarrhea; the pain is typically relieved by defecation. The diagnosis is not one of exclusion; it can be made based on the answers to a few key questions and the absence of "alarm" symptoms. Fiber therapy, the elimination of particular foods, and regulation of bowel function can help relieve symptoms. Tegaserod or polyethylene glycol can be used to treat IBS with constipation. Loperamide and alosetron are of benefit in IBS with diarrhea (although the latter carries a small risk of ischemic colitis). Low-dose tricyclic antidepressants may be used to treat the abdominal pain associated with IBS. Probiotic therapy or rifaximin may help reduce bloating. Psychological therapies seem to improve well-being in patients with IBS.
With the significant rise in methicillin-resistant Staphylococcus aureus (MRSA) infections, a small rise in the number of cases of Clostridium difficile colitis appears to be an unfortunate but unpreventable consequence of using the few effective antibiotics remaining that can be prescribed in the outpatient setting.
A 2-year-old boy was brought to the emergency department by his mother after he slipped and fell in the bathtub. The boy's father, who had been bathing the child when the injury occurred, reported that he had briefly turned his back while the child was attempting to drink from the hook-shaped faucet. The child had jerked his head upward when he fell, thus causing the sharp edge of the faucet tip to lodge in the soft floor of the mouth beneath the tongue. The father, in desperation, wrenched the faucet from its base and then was able to remove the tip from the child's mouth. During the removal process, the child reached up and also cut his finger on the sharp edge of the faucet.
For several days, a 38-year-old man has had an increasingly painful swelling behind the right knee. He runs several times a week. He has hypertension but no history of trauma or periods of inactivity, and no chest discomfort or shortness of breath. He drinks alcohol occasionally but does not use tobacco or illegal drugs.
A 40-year-old Hispanic homemaker is admitted with a 3-week history of high fever, chest pain, and a dry, irritating cough. Her illness began insidiously with increasing right upper chest pain that is sharp, pleuritic, and rates a 6 on a pain scale of 1 to 10. The pain is associated with temperatures of up to 38.8°C (102°F) and chills, rigors, and profuse sweating that increase in the evening. Worsening dyspnea has been accompanied by a drop in effort tolerance.
US researchers recently reported initial phase 1 results from 2 vaccine candidates that successfully produced immune responses in healthy uninfected adults (Gibian JJ. United Press International. November 16, 2006). Eventually, the approach may be used to protect against HIV infection. Barney Graham of the NIH Vaccine Research Center and colleagues performed the tests (Graham BS, Koup RA, Roderer M, et al. J Infect Dis. 2006;194:1650-1660; Catanzaro AT, Koup RA, Roderer M, et al. J Infect Dis. 2006;194:1638-1649).
A 68-year-old woman with type 2 diabetes mellitus presented with a sore throat of 3 days' duration and progressively worsening dysphagia to both solids and liquids, including her own saliva. She denied consumption of steak or fish with bones. Attempts to swallow caused her to grimace. Her voice was normal and her airway was clear, but tenderness was noted when the larynx was moved side to side.
A 41-year-old woman presented to the emergency department with abdominal pain and vomiting of 1 week's duration. She had a history of surgery for bowel malrotation at age 11 days.
Avian influenza primarily affects wild birds and domesticated poultry. Humans acquire avian influenza viruses chiefly through direct contact of the mucous membranes with secretions or excreta from infected birds or contaminated poultry products. The upper respiratory tract and conjunctivae appear to be the main portals of entry. Influenza pandemics occur when new virus subtypes emerge and become readily transmissible among humans. On average, pandemics occur about 3 or 4 times per century. Avian influenza is not a pandemic influenza. It is not easily transmitted among humans, and it has not been found in the United States. Therefore, at present, the risk to persons in this country is considered low.
